Forest Hill (森丘, Forest Hill) is a sub-world found in the Light Realm within Adventure Mode in Super Smash Bros. Ultimate. It is located on the southeast of the map. It is inspired by the Monster Hunter world. Rathalos is fought here, and Toon Link is captured here. Rathalos will move around on the map, and will go to the plateau where he can be fought once approached from behind. The area's background music is Proof of a Hero ~ 4Version.
The Spirits found here are generally characters found in grassy areas; the majority are animals, reflecting the Monster Hunter series. Several Spirits also have wings, much like Rathalos itself.
The boss of this sub-world is Rathalos. Defeating him grants players the Rathalos spirit.
Toon Link can be freed here.
